Application filed March 29,

T0 @ZZ whom/n t may concern:

Be it known that I, LUC HOUZE, a citizen of the United States, and al resident of Hart-` Jford City, in the county of Blackford and State of Indiana, have invented anew and useful Improvement in Glass-Tanks, of whichl the following is a specification.

This invention relates to an improvement in glass-tanks.

The aim and purpose of this invention is to construct a tank with cooling devices, so that the interior 'of the tank can be preserved against the intense heat and the life of the tank lengthened. i

A further purpose is to provide-means to convey cool water against the bricks forming the tank for cooling the bricks and preventing them from being burned or destroyed by the heat.

A still further purpose is to provide means for always keeping thewater cool and at an even temperature and providingr means for regulating the supply ofthe water. p

These and other purposes not hereinbefore mentioned are accomplished by the construction illustrated in the accompanying drawings, wherein like letters otreference indicate corresponding parts-'in the several views, and in which- A Figure l is a vertical central longitudinal section through a glass-tank', showing my improvements appliedthereto. Fig. 2 is a horizontal section onthe line2 2, Fig. l. Fig. 3 is a vertical cross-section on the line 3 3, Fig. l. Fig. 4 is a detail viewof the supporting means for the cooling-pipes and a brickin position, showing the shape of the brick'and mol-.- ten glass thereon afterthe tankV hasvbeenin use. Fig. 5is alongitudinalhorizontal section through the cooling-mpeg. and Fig. 6 is a section similarto Fig. 3, showing a modified form of arrangement of cooling-pipes.

In the drawings, A designates the meltingcompartment, and B the gathering-compartment, of aglass-tank. -B designates the gathering-rings, and B the channel or passageway connecting the two compartments, all of the ordinary construction.

In the melting of glass the melting-compartment is always the hottest, and in this compartment the bricks are more liable to burn out. I also ind that the greatest amount of 1901. serialuatasw. (Numan.)

heat is near the upper surface of the glass and the greatest amount of damage to the bricks is at that point. lItherefore place my cooling-pipes inthe melting-compartment near thesurface-line of the molten glass. While IV will now describesuch a construction, it is obvious that I can Vary the arrangement and location of my cooling-pipes and place them both in the melting and gathering compartments and also in the passage-way and arrangev them toentirely cover the side walls and also the bottom, if thought desirable, in certain constructions of tanks.

The buckstays of the tank consist of the two channel-bars C C', secured together by Ineansoflbolts in the usual well-known Inanner, and the upper ends of these buckstays are connected by the usual tie-rods C". Between these channels C C ispositioned an inwardly-extending plate D, which is secured to the channels by means of bolts D. By this construction the plate is rigidly secured to the channels and supported thereby. These `plates areat a sufficient height from'the bottom ofthe tank to be adjacent the upper surface of the molten glass and extend inwardly from the side and end bars of the melting compartment, as plainly shown in Fig. 2. The inner edge of thesepla'tesis provided with two semicircular grooves 'I)l where two coolingpipesare used. -Within each groove is positioned a cooling-pipe'F.. f By referring to Fig. 4 it will be 'seenthat these grooves cover about one-half-of the periphery of the pipe. The outer surfacesl of the pipes are covered witha brick F, which is provided with semi- `'circular grooves F', which Iitaround the remaining portion of the periphery of the pipe. These bricks F are supported by a wall F, which rests uponthe bottom of the tank.l By referring to Fig. 2 it will be seen that these cooling-pipes and bricks extend' along the side and end walls of the melting-compart- 95 ment. By referring to Fig. 5`it will be-seen that these cooling-pipes have an inner'pipe E', which acts as an inlet for the cool water. The rear end of the pipe E is provided with a cap E, which is screwed thereon. The loo front end is provided with a cap Gr, which has an annular flange G' of smaller diameter than the cap extending outwardly. The outer ond of this flange is screw-threaded and is provided with a cap G, screwed thereon. These caps G G are provided with a central opening, through which passes the inlet-pipe E. Located between the outside of the pipe E' and the interior of the iiange G' is a stuffing Gr", so that a tight joint is formed to keep the water within the pipe E. Extending inwardly from the cap E is a screw-threaded stud E". The rear end of the inlet-pipe has its interior screw-threaded and is screwed vonto the stud E". Adjacent the rear end of this pipe are a series of perforations Em. E is provided with an outlet-pipe H adjacent the inlet end of the pipe E.

By referring to Fig. 2 it will be seen that' there is an opening K in the walls between the melting and gathering compartments of the tank. The front ends of the cooling-pipes located on the side walls of the melting-compartment terminate in this opening K.- The inlet-pipe E in the opening is provided with an elbow I, and the pipe extends outward away from the furnace and is provided with a controlling-valve I. also provided with a controlling-valve J.

The pipes located on the end wall of the melting-compartment are constructed in a similar manner to the pipes on the side walls. The inlet-pipe E is provided with an elbow L at its front end, and the pipe then extends away from the tank and is provided with a valve L. The outlet-pipe is also provided with a valve M.

In the construction of cooling-pipe as described the cool water entering by the interior pipe E' and then passing to the rear end and escaping through the perforations Em into the outer pipe and then returing to the front end and passing out through the outlet-pipe H, I am enabled to always keep the water inboth pipes cool and at an even ternperature. The cool water entering in the pipe E will cool the water in the larger pipe E, surrounding the same, and prevent the outer pipe from becoming too hot and melting. It also makes an even iiow of water in the pipe, and as the outer pipe is'kept cool it will also keep the adjacent bricks F cool. By having the inlet-pipe E and outlet-pipe H the same size the pipes are constantly kept full of water.

I find that after the tank has been in use for a period that the intense heat within the tank will have a tendency to melt the brick F, so that it will gradually conform with the contour of the pipes E, as shown in Fig. 4. When these bricks become sufficiently thin,

The outer pipe The outlet-pipe H is they will become cool all the way through and make the molten glass N chill, as shown at O, forming a covering for the brick, so that the same will last for an indefinite period. Inasmuch as the tank is in heat for an entire season or iire, or from fall until spring, any means which will prevent the bricks from burning out during this period is of great advantage. The tanks as now constructed are liable to burn out at any time, and when it is necessary to replace any bricks the heat has to be withdrawn, thereby wasting much time and material. By this construction the bricks being kept cool cannot burn out and will last a whole iire, if not longer. f

Resting on top of the plate D is a longitudinal plate P. On this plate the base of the arch R, forming the top of the tank, rests.

In Fig. 6 I show a modiiied form, wherein the cooling-pipes extend down to the bottom of the tank and a series of cooling-pipes S are disposed beneath the bottom of the saine.

I am aware that many Aminor changes can be made in the construction and arrangement of parts without in the least departing from the nature and principles of my invention as claimed.

Having thus described my invention, what I claim as new, and desire to secu re by Letters Patent, is-

l. The combination with a melting-tank, of a cooling-pipe within the tank consisting of an outer shell having an outlet adjacent one of its ends and both of its ends closed, astud extending inwardly from the closed end of the vshell farthest away from theoutlet, an inletpipe extending into the shell through the end nearest the outlet, the inner end of the inletpipe being secured to and supported by the stud and provided with a series of perforations adjacent its inner end.

2. A glass-melting tank provided with cooling-pipes, supporting-bars on the outside of the furnace, a plate secured to the bars and provided with semicircular grooves, and bricks on the interior of the furnace alsopro vided with semicircular grooves registering with the grooves in the plate the cooling-pipes being located in the grooves in the plate and bricks.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.

LUC I-IOUZE.
